Example: Chr(53) & Chr(53) & Chr(54) & Chr(100) & Chr(52)
to a readable format. I understand that this can be easily accomplished by writing in the ascii code into the code will do it but I am trying to create a more interactive method of doing it so I can copy and paste a long length of code into a textbox and have it update a label with the conversion.
I'm looking to create a simple program with 1 text field, 1 button, and an area to display what is happening and if there were any errors.My goal is to be able to delete user profiles stored on a network drive by simply putting in the users ID and hitting the button.I'll use my own id as an example:If I put mdesieno in the txt box and hit the button, I'll need the button to map to the network drive and delete mdesieno.corp and mdesieno.v2 I would like the bottom half of the window to display text like:
"Deleting User Profile mdesieno.corp" SUCCESSFUL
"Deleting User profile mdesieno.V2" SUCCESSFUL
To me this seems pretty simple, but as I said, I do not know VB yet. Is there code out there that is already written to do something like this?
Is there anyone can post a simple code using vb,that start building a simple games ?

View 1 RepliesI want a multi line textarea using VB.net.I have used textarea in html before but I have never used it in VB.net I tried:
<text area id="TA" cols="100" rows="20"></textarea>
I introduced space between text area only coz I cud not write it other wise in this forum.. in my code there is no space. But I cannot change the value of textare using my code behind file.
Something happened to my project and it got all messed up. I am not sure what happened, but the form I was working on only shows the code and not the project itself(where you design it). I am working in VB2008 Express Edition and do not wish to start over. What happened to my form?
View 6 RepliesI've search for hours on Google but could find a solution.want a clickable area (that can handle MouseClickEvent, DoubleClickEvent, etc...) that is transparent, hence you can look through it.For example:I have Form1 with a bunch of buttons, text fields, etc. I want a clickable area that is over the whole Form1 (thus over all the buttons, etc).If you click this area, the clickEvent for this area should be could and not the eg: button underneath this area.Most importantly of all the area must be transparent, thus all the buttons, textfields, etc underneath the clickable area should be visible. Something like a panel or pictureBox that you could put over the buttons would be ne, but a if you drag a panel/pictureBox over a button, the button is invisible, and if you say send to back, the event of the button will be called and not that of the clickable area.
View 14 RepliesThis is a problem like the puzzle - "find minimum number of coins to completely cover a piece of paper".
The difference is:
in my case RADIUS of the coins is variable (but all coins should have same radius).
Real scenario:
1. I need to draw circular shapes on a rectangular image.
2. Number of circles (N) is CONSTANT/ User input
3. Size of image (S) is CONSTANT/ User input
4. The program should find the MINIMUM RADIUS (R) that is needed to draw N number of circles on an image of size S, so that, the image is completely hidden behind the circles.
This is NOT a puzzle/assignment that I'm trying to solve.This is part of a larger project that I'm working on.
I don't need any drawing code. I just need the code/algo to find the radius.
I've been working with System.Drawing for awhile and like to think I have a good handle on it; I've created classes that draw grids, write text in gridboxes and rectangles, convert rectangles to circles, fill areas with color, etc. What I don't have is any sense of artistry at all, and I don't have the slightest clue how one would use System.Drawing to draw a rectangle and then color/slope the edges so that it looks like a System.Windows.Forms.Button would, or how to make it look like it's inset deeper than the surrounding Form, like setting a Panel's BorderStyle to Fixed3D.
View 3 Repliesi have a program with the ability to save view and scan images. i am currently working on making work area's. so i have two list box's. listbox one is for the image area name. listbox2 is to list the pages in selected image area (mouse click). i have created the form to show you and i will post a link below. i have started trying to do it but have got stuck. i use an input box to give the image area's names. but thats as far as i have got at the min.

View 1 RepliesI am currently writing a program in Visual Basic 2008 express edition to read and write to tags on an Omron PLC. I am using the DeviceXPlorer OPC Server V4.1.1.1 program to connect to the Omron PLC. I have made two programs, one is a form program which works fine, two is a windows service program where it does not let me connect to the OPC Server. The connection code is identical, the only difference is the windows service code is called by a timer. The timer works fines and jumps into the connection code, but stops at the line

Trying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.
Public Class Form1
Dim Mapx As Integer = 600
Dim Mapy As Integer = 2000
[code]....
Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.
I designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?

I'm a rookie in Visual Basics 2008 and i am trying to make a program to communicate and read tags from an Omron PLC. I am trying to connect to the PLC via devicexplorer opc server, because it can let me read DInts and Reals from the PLC tags. I have referenced Microsoft ActiveX Datas Objects 2.5 Library and OPC DA Automation Wrapper 2.02. I have made some code which connects to the PLC "in a form", but I cannot use the same code and connect through as a Windows Service program.Here is my code,
Public Sub OpcConnect(ByRef Items() As String, ByVal PLCType As Integer)
Dim j As Integer
Dim TempSvrHandles As Array[code].....
Note: this code is run in a timer on the windows service, it connects properly to the "RSLinx OPC Server", but "Takebishi. Dxp.1" (devicexplorer shortcut) exits the sub routine at MyServer.Connect(PLCServer) ' connect to the opc server.

There are 37 elements in the list - 37 Street Type Abbreviations with their associated Descriptions. The lookup will only happen once. The input lookup field is in a single field: stType.

Two dimensional array let me initialize the values, but searching an old school loop.
